X.25 over ISDN B Channel
Verifying Your Configuration
You can verify your configuration to this point by confirming the ISDN line status
as follows:
Step 1 From the privileged EXEC command mode, enter the show isdn status
command. You should see command output similar to the following:
Router# show isdn status
The current ISDN Switchtype = basic-5ess
ISDN BRI0 interface
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 80, State = MULTIPLE_FRAME_ESTABLISHED
Layer 3 Status:
No Active Layer 3 Call(s)
Activated dsl 0 CCBs = 0
Total Allocated ISDN CCBs =
Step 2 Confirm that the “State = MULTIPLE_FRAME_ESTABLISHED” message
appears in the command output, as shown in the example.
Note In some cases, you might see a “State = TEI_ASSIGNED” message
instead of the “State = MULTIPLE_FRAME_ESTABLISHED”
message. This message also means that the ISDN line is correctly
configured.
Step 3 If you do not see the message, do the following:
a. Make sure that the router is correctly cabled.
b. Make sure that any external Network Termination 1 (NT1) equipment is
functioning correctly. Refer to the documentation that came with the NT1.
c. Make sure that the ISDN line is correctly configured. Check with the ISDN
service provider.
Step 4 To continue configuration, reenter global configuration mode.
